Employee who works some of the week only (4-5)

Ross

I believe the answer is:

part-timer

(Other definitions for part-timer that I've seen before include "One working reduced hours" , "Casual worker" , "worker on reduced hours" , "One not working the whole week" , "One working less than a full week" .)

I've seen this clue in The Times.
